The protein encoded by this gene is involved in mRNA splicing and may play a role in the determination of alternative splicing. The encoded nuclear protein belongs to the splicing factor SR family and has been shown to bind with and modulate another member of the family SFRS12. Alternative splicing results in multiple transcript variants. In addition two pseudogenes one on chromosome 17 and the other on the X chromosome have been found for this gene.[provided by RefSeq Sep 2010]
